Residents in Swindon are set for a dry and warmer-than-average week as high pressure dominates the area from 20 April to 26 April 2026. According to the Met Office, temperatures will climb steadily from 14°C on Monday to reach 19°C by Thursday, remaining above the typical April average of 12.8°C to 14°C.
While the settled, dry weather is ideal for outdoor activities, the Met Office has issued a warning for high pollen levels. Senior Scientist Lucy Neal explained that the current warm, dry and sunny conditions, combined with light to moderate breezes, are perfect for trees to release pollen and for it to travel longer distances. Hay fever sufferers should be prepared for high counts of birch pollen, with the oak season also beginning.
Those planning to be outside should also be aware of moderate UV levels throughout the week, with officials advising the use of sunscreen during the middle of the day. Winds will be primarily from the east-northeast, with gusts expected to reach 33mph on Wednesday before easing as the weekend approaches.
Despite the high pollen count, air pollution remains low, allowing for normal outdoor plans such as gardening and walks. Rain is unlikely, with a less than 5% chance forecast for most of the week, although there is a slight 10% possibility of rain on Saturday and Sunday evenings.
